I dont think AMD is taking a direct aim at external media storage, sure thunderbolt is heck better then USB3 for that, but to say that thunderbolt can take over from DisplayPort or even sata3 is a bit much, for a single point to point connection it's great but when you start to daisy chain these devices, having a single connector serve all your connection needs maybe unwise, especially if you plan on chaining more then one display
and i maybe wrong, but i yet to see cooper produce any kind of light, going optical will likely mean compatibility issues, might as well call it a different product altogether, i dont know maybe something like lightpeak....
